The Chaser

"The Chaser" is episode 31 of the American television anthology series The Twilight Zone. Opening narration Plot Roger Shackleforth is desperately in love with Leila, an aloof woman who dismisses his affections. A stranger hands him the business card of an old professor named "A. Daemon", who can help with any problem. Roger visits Daemon, who after some resistance and suggestions that Roger will regret it, sells him a love potion for $1. Roger administers it in a glass of champagne; Leila falls madly in love with him and marries him, but soon her love becomes stifling. Roger returns to the professor to buy poison for $1,000, all of Roger's savings. Daemon cautions Roger that the "cleaner" is odorless, tasteless, and completely undetectable, but must be used immediately and completely, or the user will lose his nerve and never again have the courage to try it. After Roger leaves, the professor muses, "First, the 'stimulant'... and then the 'chaser'."
